OBJECTIVES To determine whether the percentages of major CD4+CD161+ T-cell subsets [T-helper (Th)17, Th1, and Th17/Th1] in peripheral blood are correlated with disease activity of rheumatoid arthritis (RA). METHOD In 42 RA patients and 15 healthy controls (HCs), the percentages of interleukin (IL)-17- and/or interferon (IFN)-γ-producing CD4+CD161+ T cells(More)
OBJECTIVE To investigate the relationship between the uptake of technetium-99m methoxyisobutyl isonitrile ((99m)Tc-MIBI) and the expression of multidrug resistance genes mdr-1 and MRP in lung cancer so as to guide chemotherapy. METHODS Eighteen lung cancer patients were given 1 110 MBq(99m)Tc-MIBI intravenously. Chest single-photon emission-computed(More)
A novel electrochemical detection architecture was investigated for enzyme immunoassay sensors. Microchips with dual-ring working and counter electrodes, and a sensing cavity chamber were made on glass slides. The glass surface of the microchip was coated by 3-aminopropyltriethoxysilane (APTES). Goat IgG, as a example, was covalently captured on(More)

BACKGROUND To study digital subtraction angiography ( DSA) features of pulmonary hypoperfusion in lung cancer with cancerous invasion of central pulmonary artery ( CICPA) . METHODS Twenty-six cases of lung cancer combined with CICPA underwent pulmonary DSA. The DSA features of pulmonary hypoperfusion, including pulmonary vessel signs and lung parenchyma(More)
BACKGROUND To investigate the incidence of pulmonary artery hypertension secondary to cancerous invasion of central pulmonary artery (CICPA) in lung cancer and the diagnostic value of CT on pulmonary artery hypertension. METHODS Twenty cases of lung cancer combined with CICPA underwent pulmonary artery pressure measurement through right heart(More)
BACKGROUND To apply spiral CT angiography( SCTA) as imaging method of pulmonary angiography and study the imaging findings of cancerous invasion of central pulmonary artery (CICPA) in lung cancer patients by means of spiral CT pulmonary angiography (SCTPA) . METHODS Thirty patients with central type of lung cancer proved by bronchoscopy biopsy or surgery(More)
BACKGROUND We determined the minimal alveolar concentration (MAC) of sevoflurane inducing an isoelectric EEG in 50% of adult subjects (MACie). METHODS We included 31 middle-aged subjects; 30 subjects finished the study protocol and received sevoflurane at preselected concentrations according to a modified Dixon 'up-and-down' design starting at 1.7 vol%(More)
BACKGROUND Owing to the limitation of monolayer tumour cells or transplanted tumor in radiation biology, multicellular spheroid (MTS) as a model of entity tumor had a wide range of application. This research aims to study the growth characteristics of A549 lung adenocarcinoma MTS so as to choose the best ones to perform experiments. METHODS 1.75×10⁷ A549(More)

BACKGROUND To study the collateral pathways of superior vena cava syndrome ( SVCS) . METHODS Thirty-one spiral CT phlebograms of patients with SVCS were obtained. Superior vena cava was divided into upper and lower segment by azygos arch, and the collateral pathways were divided into anterior and posterior groups according to their sites in the chest(More)
